Thing is putting 90% equipment together does not guarantee 90% performance, in fact a mixture of lower rating could give much better results, as how they interact with each other is more important than how good they are individually, (You will find on many forums users who picked all best buys or 5 stars etc. that are not satisfied with the combination) as to WHF reviews (Or any reviews for that matter) anything that has 3 stars or more (50% or more) should be on your audition list, not just those that come out top.
